After years studying the icy waters of the Southern Ocean with floating robotic monitors, a consortium of oceanographers and other researchers is deploying them across the planet, from the north Pacific to the Indian Ocean.

The project known as the Global Ocean Biogeochemistry Array, or GO-BGC, started in March with the launch of the first of 500 new floating robotic monitors containing computers, hydraulics, batteries and an array of sensors scientists say will relay a more comprehensive picture of the ocean and its health.
